TPS259461LRPWR Description

Short technical summary and product information.

The Texas Instruments TPS259461LRPWR is an active eFuse with a wide operating input voltage range from 2.7 V to 23 V, and an absolute maximum continuous voltage of 28 V. It provides overcurrent protection with a current limit adjustable from 0.5 A to 6 A, and a nominal current rating of 5.5 A. The device features integrated back-to-back FETs with a low typical on-resistance of 28.3 mΩ.

 

Key features include adjustable overvoltage lockout (OVLO), adjustable soft start, current monitoring, a fault output, power good signal, and reverse current blocking when off. It also incorporates thermal shutdown and adjustable undervoltage lockout (UVLO). The eFuse responds to overcurrent conditions by current limiting and offers auto-retry or latch-off fault responses. Its typical quiescent current is very low at 0.428 mA.

 

Packaged in a 10-VQFN-HR (2x2 mm) surface mount package, the TPS259461LRPWR is suitable for applications requiring robust power protection. It holds UL recognition for IEC62368 and UL2367 standards. The operating temperature range is -40°C to 125°C (TJ).
